THE BROCH CULTURES OF ATLANTIC SCOTLAND: ORIGINS, HIGH NOON AND DECLINE. PART 1: EARLY IRON AGE BEGINNINGS c.700–200 BC

Abstract

Summary. A new overview of the broch and wheelhouse‐building cultures is offered because recent comparable attempts have omitted substantial amounts of relevant data, such as discussion of the most plausible broch prototypes and of the details of the material cultural sequence, particularly the pottery. Well dated Early Iron Age roundhouse sites have often been described, but promontory forts of the same period, showing the specialized broch hollow wall, have not. The example at Clickhimin, Shetland, is now reliably dated to the sixth century BC at the latest and the associated pottery shows clear links with north‐west France. Another unexcavated example in Harris can be restored in some detail and shows how these sites were probably used. The pivotal role of Shetland in the emergence of the new culture is confirmed by the early dating of the broch at Old Scatness to the fourth/third centuries BC. However, a separate development of the round broch tower seems also to have occurred in the west, in the third/second centuries BC. English Early Iron Age pottery is also prominent in some of the earliest sites in the west and north. The picture is of a dynamic, maritime zone open to influences from several remote regions.
